Hot water space heating is possessecd of a great deal of merits technically as well as economically. But, as far as manufacture, oparation and heat supply system are concerned, it will be very irrational to retrofit a steam boiler for use as a hot water boiler for space heating. The above view js amply demonstrated in this paper to bring it to the readers' attention.

Retrofitting of the100MW TCDF condensing steam turbine includes installing butterfly valves in the inlet of LP cylinder to keep out the bleeding pressure, safty valves across the butterfly valves to prevent overpressure in HP cylinder exhaust zone and connecting extraction piping to the cross-over pipes between HP and LP cylinders. The extraction pressure control system was designed to maintain the back pressure of HP cylinder according to the main steam flow-back pressure relations at designed condensing...

Retrofitting of the100MW TCDF condensing steam turbine includes installing butterfly valves in the inlet of LP cylinder to keep out the bleeding pressure, safty valves across the butterfly valves to prevent overpressure in HP cylinder exhaust zone and connecting extraction piping to the cross-over pipes between HP and LP cylinders. The extraction pressure control system was designed to maintain the back pressure of HP cylinder according to the main steam flow-back pressure relations at designed condensing operat ion.The conceptual and structural design is introduced briefly in this paper . During the past 8 years of practice, the average heating extraction of this machine has been about 160 T/'h in the heat ing seasons. No major defects or outages have ever occured in the installment and control system. Rated heating capacity is 200 T/h of 2.3ata steam at an expense of 19MW of electric output loss. Possible heating capacity at 100 MW elecfric output is 110 T/h . Performance tests and fuel conservation are analysed.

本文概括地总结100兆瓦机组改型后八年运行实践的安全性及热经济性。扼要地介绍采用导汽管抽汽方法及试验考核的数据,分析了机组实际达到以及能达到的热经济水平,在保持原通流结构,调峰能力及铭牌出力时,可望达到的节能效益。结果表明,节能效果显著,本机组改型的经验对研制适合我国国情的采暖机型,有参考价值。

While explaining the necessity of water dynamic modelling of a hot water boiler, the article gives a description of the design philosophy of'the test facility and the water dynamic characteristics of four typical types of return-water circuit now adopted for domestic units. As shown by the test results, the supply of water at one side of the drum only and with natural circulation return-water circuit will result a better water dynamic performance and the advantage of eliminating the potential water leakage at tube plate (or potential weld crack) and also the swelling at drum bottom. The results obtained from the test have been applied in the design and retrofitting of packaged hot water boilers.

本文阐明了进行水动力模拟试验的必要性,介绍了试验装置的设计原则,并用图和表格清楚地说明了国内四种典型回水布置方式的水动力特点。试验结果表明,锅筒单侧进水并保持原有自然循环的回水布置方式其水动力工况是比较好的,有利于防止管板漏水(或焊缝拉裂),也有利于防止锅筒底部鼓疱。试验结果已初步用于指导快装锅炉型热水锅炉的设计和改造。
